Overview
Fungal meningitis usually presents with progressive symptoms of headache, low grade fever and fatigue. If left untreated, neurological complications might occur.
Natural History, Complications and Prognosis
Natural History
Fungal meningitis is rarely found in immunocompetent patients. It usually occurs in patients with immunosuppression like patients with HIV and transplant patients on immunosuppression and long term steroid therapy. The onset of symptoms is progressive and the course of the infection is protracted. The patients tend to present with symptoms like headache, low grade fever, fatigue and even weight loss[1]. This obscure presentation might cause delay in the diagnosis and in the initiation of the appropriate treatment.
Complications
The following are some complications that may follow fungal meningitis:[2][3][4][5]
- Abscesses
- Bone invasion
- Fluid collections
- Neurological deficits
- Ocular invasion
- Papilledema
- Seizures[1]
- Neurodevelopmental delays in children
Prognosis
The mortality associated with fungal meningitis is high. Better prognosis is associated with early diagnosis, early initiation of the treatment and compliance of patients with medications.
Prognosis of cryptococcal meningitis
Prior to the introduction of amphotericin B therapy, cryptococcal meningitis was almost always fatal. Now, although most of these patients can be cured with course of intravenous amphotericin B, the optimum duration of therapy is often unclear, and there is still a significant percentage of early deaths and late treatment failure.[6][7][8]
Increasing levels of the following worsens the prognosis of HIV-negative cryptococcal meningitis patients with acute/subacute onset
- Ratio of CSF glucose/blood glucose
- Impaired consciousness and
- Hospitalization length
Factors associated with a bad prognosis of coccidioidal meningitis are:[9]
hydrocephalus, non-Caucasian race, or presence of an underlying disease.
The mortality of cryptococcal meningitis is high (10-30%).[10]
Prognosis of coccidioidal meningitis
Prognosis is worst in patients with sevral sites of extrapulmonary dissemination compared to patients who have only meningeal involment.[11] Prior to the introduction of antifungal therapy coccidioidal meningitis wa almost always fatal.[11]
